it To all whom-it may concern: Q Be it known that I, Josnrr V.Biim Aun,

NITED szrATEs PATENT curios;

Josririi v. BBETAUD; or PHILADELPHIA,-BENNSYLVANIA.

a citizen of theRep'ublic of France, residin at Philadelphia, in thecounty of Phila-- dephia and State of Pennsylvania, have inventedcertain new and useful Improvements in Ladles, of which the following isa specification.

The present ractice of pouringmoldsin iron and steel oundries, makingsmall and medium'castings, is to fill a large ladle at -the cupola orconverter and to empty' itscontents into small shank ladles carried bytwo or'three men, the pouring proper being thus made by hand. The useof'these small ladles is resorted toon account of the. impossibility toget from a large ladle. a gentle even stream of metal easily controlled,and

i to direct this stream in the mold gate without euttin of the sand orundue spilling of metal. T is is however,- an unsatisfactory 7 methodowing to the chilling of metal and formation of skulls on the handladles, the

irregularity of the pouriii temperature andconsequently of the shrin ageof the'castings, the exhausting character of the work and excessive-heatradiated upon thenien and the expense, of labor. attending to thepouring itself and to the keeping up of hand ladles. 1

The rapid development of the molding machine with its tremendous outputhas further emphasized the need fora more modern method of pouringeliminating manual work. These consi erations will serve to showflthenewness and usefulness of my improved ladle'liereinafter described.

My invention relates to lip pouring ladles suspended from a crane or anoverhead trol-- ley, and the objects of my improvements are rovide'amediumsized ladle. easily conolled by one man, capable of deliverin avertical steady stream of metal, theposition of which does not changedurin' the tilting of the ladle, with consequent ability of hav- .}ingthis ladle filled at the eupola or conset side by side, oscillatingaround their res'pe'etive lips toward one another, and thus balancingeach other in all positions .of

pouring. These bowls are kept. at a proper LADLE.

distance. apart so that their streams unite and further I'use a funnelto give to the resultin stream a uniform size, independently o' thespeed of tilting, which funnel also acts as a skimming device.

I have illustrated on the accompanying sheet of drawings, a ladleembodying the producing the tilting of the bowls can be devised. w

Fig. 5is a detail horizontal section on line 5-5 of Fig. 1, and,- Fig. 6 is asimilar'view on line 66 of Fig. 2.

Similar letters refer to similar parts throughout the several views.

The ladle is formed by a supporting frame a, hooked to a trolley orcrane chain by the v -above features-although numerous means of s linkI). This frame carries two rollers, c and c and has a downwardextension. d. The bowls!) and e lined inside with a refractory materialare suspended from the rollers 0' by means of the chains f and f, on oneend of which are attached the eye bars 9 and g, journaled at h and it onthe back of the. bowls. The other end of the chains f and f is connectedwith thelink 2' which is rigidly fastened to the U-shaped bail j, thelink 11 beingguided in the frame extension 01 by means of the rollers v,'v and w. Each end of the bail j carries a lip spacing member is, one infront of the bowls and one on the back in Fig. 1. These spacing-membersact as bearings for the ends of shafts l and Z which are riveted to thebowls underneath their respective lips. Each bowl has thus I threebearings,-one on each side of the li at V Z, on a line perpendicular tothe plane 0 the drawing in Fig. l and one central bearing at h on theback. Each bowl. is then in stable equilibrium. The hooks m and mprevent any accidental withdrawing of the shafts 1 from their bearings.

The ends of bail are conneeted by'a light frame 't forming sup rt for aceii'tral fun iiel or nozzle 'u, which-regulates the size of the streamof metal. The tilting is provided by a pinion a, shaft 0 and hand wheehpI carried by the frame extension the said ing of the bowls.

- It will be seen from-Filgs, 2 and 3 that during the tilting of theyadle, the respective centers of gravity of the bowls are not materiallyraised,. the efl'ort. necessary to tilt them, being consequently very,small. In

this case, the funnel has a vertical downward movement during thepouring.

The ladle being symmetrical in respect to the vertical center line, forevery position of the bowls, the center of gravity of the whole systemis always on this same line, and the equilibrium is not'disturbed by thetilt lips being conveniently kept apart by time spacing. members k,their respective streams of metal will unite and form asingle streamiilgjays situated on the center line of the The -funnel receives themetal from the bowls and delivers it in a stream of uniform size,irrespective of the speed of tilting of the bowls.

This ladle produces a steady even stream of metal always under perfectcontrol,- and owing to its, positive operation, it can be used to pourthe smallest work with ease; The mo ds being lined up under the overheadtraveler, one man grasps the hand wheel and proceedsto dothe pouringwith" speed and precision by stopping the ladle funnelover each gate,any mg unnecessary.
